rubber(synthetic and natural), polypropylene, wood, glass, plastic
Natural polymer: shellac, amber, natural rubber, cellulose Synthetic polymers: synthetic rubber, Bakelite, neoprene, nylon, PVC, polystyrene, polyethylene, polypropylene, silicone, etc.
Ropes are classified in 2 categories. The first is synthetic or natural materials such as cotton or hemp. The other type is non-synthetic rope which is made from non natural materials such as polypropylene, nylon, and polyesters. Synthetic fibre ropes are significantly stronger than natural fibers, but also have disadvantages.
Polypropylene is made primarily from oil or natural gas, though it can be made from coal.
